Frauenquote

29. May 2020

Disclaimer: Ich bin ein Mann und eigentlich sollten wir Männer bei diesem Thema gepflegt die Fresse halten, weil wir nicht betroffen sind! Warum schreibe ich jetzt trotzdem etwas dazu? Letztens hat mein Arbeitskollege Stefan Rauch über das Thema Frauenquote geschrieben. Woraufhin ich kommentierte dass es meiner Meinung nach nur mit Quote gehen wird: Leider funktioniert es nur mit Quote. Das zeigt ja schon alleine wie wenig sich in den letzten Jahrzehnten getan hat.…more

Please Use Semantic Versioning

22. May 2020

TL;DR Please use Semantic Versioning and please use it right! This is a little rant about tools, libs and frameworks not using Semantic Versioning. This morning I was triggered on Twitter by the announcement of Terraform version 0.13. My first thought was: WTF! Why are you still at 0.x with a software widely used in production? Disclaimer: I use Terraform by my self and I like it. Scrolling through my time line I saw various other announcements like 0.…more

My Opinion on Zoom

15. May 2020

TL;DR: Do not use Zoom at all! If you have to: Use it on iOS or in the browser. Nowadays we use lots of video conferencing to practice physical distancing. A major player in the field is Zoom. One reason for that is the fact that they have a good software quality. At least on the surface it looks like they have. Because the inner software quality seems not that good.…more

Hardening Your SSHd With Ansible

8. May 2020

Disclaimer: This is not a beginner tutorial. You should have a brief understanding and some experiences with Linux and Ansible. Whenever you run a server in the wild wild web you should harden your SSHd setup. If you wonder why you should do that, then spin up a machine with enabled SSHd and watch the logs: Usually it takes only few minutes until the first scans and brute force attacks showing up in the logs.…more

It Is Not Just the Flu

30. April 2020

There are lot of opinions out there about SARS-CoV2 (aka. Corona). Lots of them stating that COVID-19 (the disease of a SARS-CoV2 infection) is not more than just the good ol’ flu. But this opinion is BS! Although I’m more a technical guy interested in computer stuff and security I feel the urge to say some words about this topic to provide an opposite pole. Because this ill-informed opinion SARS-CoV2 is just like the flu threatens the security of the health of my family, friends and me!…more

Blog Resurected

23. April 2020

I’ll be Back Baby Since months, no years, I desired to start writing blog posts again. I think I have to say some things some times. That’s the reason why I resurrected my blog. This involved some Terraform and Ansible hacking to get it run. I also updated the theming. I decided to choose one without JavaScript to save your bandwidth.

Interim Move to Jekyll and GitHub

16. February 2018

Roundabout two years ago I decided to get rid of Wordpress and the full stack of PHP and MySQL. About my reasons for this decision I’ve blogged here. As a result I decided to write my own simple blog solution: Uberblog. This was a weekend project which served me well, until I decided to reinstall my root server from scratch. Then the hassle with Ruby, Gems and dependency versions started. It was so much fiddling to get these quite simple Ruby scripts running again with their dependencies.…more

Agile Bodensee Conference 2012

24. November 2014

My brother has organized his first conference. It is also the first local agile conference at Bodensee in Germany. It is the Agile Bodensee on 28th of September. One of my favorite highlight is the fact that the conference fee is really cheap. The fee for the whole day is only 50 Bugs. Other highlights are the keynote speakers: Jurgen Appelo and Joseph Pelrine.

Passenger On Board

7. April 2012

In my first approach I was running the Sinatra app for the REST API of my blog (for ratings etc.) from command line. This has the drawback that the HTTP daemon integrated in Sinatra listens on a different port than the rest of the blog. This leads to same origin problems when ajaxing the REST API. To circumvent this I’ve used a small proxy script as a workaround. But now I’ve found Passenger (aka.…more

Chrome Dev Tools Reloaded

1. April 2012

Are you using Firebug or Venkman? Did you ever tried the Chrome developer tools? If your answers were yes and no you should watch this video from Google IO 2011 about the Chrome developer tools: If your answers were no and no you should consider watching the video, too. And you should think about better ways than sprinkling alert() all over you’re code and forget them there for the joy of the user.…more
